docs(fix): replace img tag with Markdown images

[mikemckiernan]

Description

The img HTML tags do not communicate to Sphinx to copy the graphic to the output HTML. As a result, all the images were missing.

Thank you Mike! It seems you are using Poetry 2 locally

We have 2 options:

1. use poetry < 2 like 1.8.2 and force push
2. merge it once chore: update Poetry to version 2.1.2 across workflows #1078 is merged

I have also faced some issues with poetry version mismatch and my 2 latest PRs are failing.

or even a third option if possible:

3. create a separate PR with dependency changes, like chore(deps): constraint nvidia-sphinx-theme ...

I moved the deps update into #1090 using poetry 1.8.2. No objection from me, it was strained to do it in this PR.

@mikemckiernan Is following OK? {W=75% align=center}

I mean does it only happen on Github?

Ugh. No. I misunderstood the MyST Parser syntax. I pushed an update that uses an image directive. TY!
